Cleaner Process and Entrainer Screening for Bioethanol Dehydration by Heterogeneous Azeotropic Distillation

Chemical Engineering Transactions, 2020
Greenhouse gas footprint of fuels is due to both the burning fuel and its production process. Bioethanol is a sustainable biofuel but it is obtained diluted in water and its dehydration consumes large amounts of energy.

Kinetic Study of Ethanol Dehydration to Ethylene and Diethyl Ether in Catalytic Packed Bed Reactor Over ZSM-5 Catalyst

Diyala Journal of Engineering Sciences, 2023
Dehydration of ethanol is one of the crucial processes as it is considered a green route for producing ethylene and diethyl ether and is promoted mainly by economics and environmental appeal.

Imaging of RNA in situ hybridization by atomic force microscopy [PDF]

, 1996
In this study we investigated the possibility of imaging internal cellular molecules after cytochemical detection with atomic force microscopy (AFM). To this end, rat 9G and HeLa cells were hybridized with haptenized probes for 28S ribosomal RNA, human ...

Integrally skinned polysulfone hollow fiber membranes for pervaporation [PDF]

, 1994
From polysulfone as polymer, integrally skinned hollow fiber membranes with a defect-free top layer have been spun. The spinning process described here differs from the traditional dry-wet spinning process where the fiber enters the coagulation bath ...

Steam-Induced Coarsening of Single-Unit-Cell MFI Zeolite Nanosheets and Its Effect on External Surface Brønsted Acid Catalysis. [PDF]

, 2020
Commonly used methods to assess crystallinity, micro-/mesoporosity, Brønsted acid site density and distribution (in micro- vs. mesopores), and catalytic activity suggest nearly invariant structure and function for aluminosilicate zeolite MFI two ...

Selective oxidation of ethanol to ethylene oxide with a dual-layer concept

Catalysis Communications, 2022
Ethylene oxide is mainly produced from fossil-based ethylene. Only minor amounts of EO are based on renewable ethanol in a three-step process consisting of an ethanol dehydration step, an ethylene purification step, and an epoxidation step.

The use of ethanol as contrast enhancer in synchrotron X-ray phase-contrast imaging leads to heterogeneous myocardial tissue shrinkage: a case report

Journal of Synchrotron Radiation
One of the main limitations of conventional absorption-based X-ray micro-computed tomography imaging of biological samples is the low inherent X-ray contrast of soft tissue.
